Osteoarthritis involves low-grade inflammation, impacting pain and joint structure. This review explores evidence for inflammation in osteoarthritis, potentially changing how we define, diagnose, and treat this condition.
Area of Science:
- Rheumatology
- Immunology
- Orthopedics
Background:
- Osteoarthritis (OA) is increasingly recognized as having an inflammatory component.
- This inflammation contributes to OA symptoms like pain and joint structural changes.
Purpose of the Study:
- To review evidence supporting the role of inflammation in OA.
- To discuss the implications of this inflammatory view for OA management.
Main Methods:
- Comprehensive literature review.
- Analysis of molecular, cellular, imaging, and clinical data.
- Synthesis of evidence on OA inflammation.
Main Results:
- Significant evidence supports a low-grade inflammatory process in OA.
- Inflammation is linked to pain, synovial changes, and structural progression.
- This perspective is supported across multiple scientific domains.
Conclusions:
- Viewing OA through an inflammatory lens is crucial.
- This evolving understanding may refine OA phenotyping and prognosis.
- It opens new avenues for targeted OA treatment development.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
